IDE (PIO mode 0) to IDE (DMA mode 0)
Please provide values below to convert IDE (PIO mode 0) to IDE (DMA mode 0), or change ↔.
IDE (PIO mode 0)
Definition: Refers to the Programmed Input/Output (PIO) mode 0 for IDE devices, with data transfer rates of up to 3.3 MB/s.
Funfact: PIO mode 0 was the earliest IDE mode, providing basic data transfer without DMA support, making it quite slow by modern standards.
IDE (DMA mode 0)
Definition: Refers to Direct Memory Access (DMA) mode 0 for IDE devices, with data transfer rates of up to 4.2 MB/s.
Funfact: DMA mode 0 allowed the system to transfer data directly between devices and memory, reducing CPU overhead compared to PIO modes.

How to Convert IDE (PIO mode 0) to IDE (DMA mode 0)
1 IDE (PIO mode 0) = 0.7857142857 IDE (DMA mode 0)
1 IDE (DMA mode 0) = 1.2727272727 IDE (PIO mode 0)
we use cross multiplication method
IDE (PIO mode 0) → IDE (DMA mode 0)
1 → 0.7857142857
1.5 → ?( suppose x)
=>1.5*0.7857142857=1*x
by simplifying
x=1.1785714286
